Stuttering and Slowdown when playing 192KHz 23 Bit Float files

[danjp2000]

Steps to reproduce the problem

Play wave file with 192Khz Sample Rate and 32 bit float format using either ALSA or Pipewire plugins.

What's going on? Describe the problem in as much detail as possible.

When I try to play any wav file that is 192Khz 32 bit float Deadbeef starts stuttering and then slows down. If I pause the playback and then un-pause the playback is fine for about 2-3 seconds and then it starts stuttering again.

This issue exists when using the ALSA direct to hardware and the pipewire output plugins. With the pulse plugin it does not stutter but is choppy.

I tried changing the ALSA buffer/period sizes and making it very small (buffer 512, period 4) makes it better but it still stutters and then starts to slow down.

If I convert the wav file to FLAC it plays back without issue. Also if I convert it to signed 24 or 32 bit wav file it plays without issue.
Also if I convert it to 96KHz 32 bit float it plays without issue. So it seems that the issue only occurs when the audio is saved as 192KHz 32 bit float.

All of the above is with the ALSA plugin.

With the pipewire plugin the 32 bit float and signed 32 bit 192Khz stutters. If I convert the file to 192/24 it plays back without issue.
